Abstract

An attachment enables a front end loader, such as a skid-steer loader, to lift, carry and dispense loads at an extended distance from the loader. The attachment includes an elongated “chute” which is adapted to carry various types of materials. A movable “ram” is fitted within the interior of the chute and may be adjustably positioned along the length of the chute. Material loaded into the chute is initially positioned in front of the ram, i.e., between the ram and the distal (open) end of the chute. Thereafter, the ram may be actuated so as to apply a force on the loaded material, thereby displacing the material toward the distal end of the chute until at least some of the material is dispensed from the chute. After forcing material off the chute in this manner, the ram may be moved back towards its original position so additional material can be loaded into the chute.

Claims

1. An attachment that enables a front end loader to lift, carry and dispense loads at an extended distance from the loader, the attachment comprising:

a chute portion adapted to carry a load; and

a ram mounted within the chute portion, the ram being adapted to move within the chute portion so as to dispense at least a portion of the load from the chute portion.

2. The attachment of claim 1, further comprising:

a base portion connected to the chute portion, the base portion having a coupling mechanism that attaches the attachment to the front end loader.

3. The attachment of claim 1, further comprising:

a hydraulic actuator adapted to apply a force on a linkage connected to the ram, the applied force extending or retracting the linkage so as to displace the ram within the chute portion.

4. The attachment of claim 3, wherein the hydraulic actuator is actuated in response to an auxiliary hydraulic pressure supplied from the front end loader.

5. The attachment of claim 1, wherein the hydraulic actuator is a double-acting hydraulic cylinder.

6. The attachment of claim 3, further comprising:

a support structure adapted to secure the hydraulic actuator.

7. The attachment of claim 3, wherein the linkage comprises a plurality of pivotally connected segments between the ram and the hydraulic actuator.

8. The attachment of claim 7, wherein the linkage further comprises:

a first segment having first and second ends, the first end of the first segment being pivotally connected to the ram; and

a second segment having first and second ends, the first end of the second segment being pivotally connected to the second end of the first segment, and the second end of the second segment being pivotally connected to a fixed location on the attachment.

9. The attachment of claim 8, wherein the first and second segments are the same length.

10. The attachment of claim 1, wherein the chute portion has a generally U-shaped cross section.

11. The attachment of claim 10, wherein the chute portion is constructed from a single sheet of material that is bent into the generally U-shaped cross section.

12. The attachment of claim 10, wherein the sides of the generally U-shaped cross section are covered with angled supports.

13. The attachment of claim 1, wherein the chute portion has a perforated region.

14. The attachment of claim 1, wherein the chute portion has a strategically placed hole for dispensing the load.

15. The attachment of claim 1, wherein the load includes at least one of a granular, chipped, cut or bundled material.

16. The attachment of claim 1, wherein the front end loader is a skid steer loader.

17. A method for transporting and dispensing a load using a front end loader, the method comprising:

attaching an attachment to the front end loader, the attachment having a chute portion adapted to carry the load and a ram adapted to dispense the load from the chute portion;

placing the load in the chute portion, the load being situated between the ram and a distal end of the chute portion;

transporting the load to a desired location; and

displacing the ram towards the distal end of the chute portion, thereby forcing at least a portion of the load off the chute portion and into the desired location.

18. The method of claim 17, further comprising:

displacing the ram away from the distal end of the chute portion after dispensing at least a portion of the load into the desired location.

19. The method of claim 17, wherein the step of displacing the ram further comprises:

connecting a linkage between the ram and a hydraulic actuator; and

actuating the hydraulic actuator so as to apply a force on the linkage, thereby displacing the ram in a selected direction in the chute portion.

20. A front end loader and attachment assembly for transporting and dispensing a load at an extended distance from the loader, the assembly comprising:

means for attaching an attachment to the front end loader, the attachment having a chute portion adapted to carry the load and a ram adapted to dispense the load from the chute portion;

means for placing the load in the chute portion, the load being situated between the ram and a distal end of the chute portion;

means for transporting the load to a desired location; and

means for displacing the ram towards the distal end of the chute portion, thereby forcing at least a portion of the load off the chute portion and into the desired location.

21. The assembly of claim 20, further comprising:

means for displacing the ram away from the distal end of the chute portion after dispensing at least a portion of the load into the desired location.

22. The assembly of claim 20, wherein the means for displacing the ram further comprises:

means for connecting a linkage between the ram and a hydraulic actuator; and

means for actuating the hydraulic actuator so as to apply a force on the linkage, thereby displacing the ram in a selected direction in the chute portion.
